IMPROVEMENT IN THE MANUFACTURE 0F FIGURED RUBBER CLOTH.

- Specification forming part of Letters Patent No. 35,902, dated July 29, 1862.

To dll whontit ma!) concern:

Beit known that I,'LORIN BURT, a. citizen of the United States, now residing in France,

lhave invented certain new and useful Improve ments in the Application' of India-Rubber in Designs upon Cloth; and I- do hereby declare and-ascertain mysaidinvention as follows, re-

` ferri'ng to the accompanying drawing, which represents a' vertical sectionof the machine cutt rough the center at rightfangles to the' rolle s, '&c.

My invention consists in the particular arrangement and combination of ',.theseveral parts' of the machine, hereinafter described,

enabling me to produce with'a'single-printing or' engraved .roll the impression ou both sides of the cloth at a'single operation, and to subsequentl-y remove all the` gum not impressed upon' the cloth in the figure rcqnired'after the impression is lmade.

\ The vannexed drawing is avertical'sec-tion -cut through the center of. the machine. The arrows indicate the direction theV cylinders turn smithe course of the cloth through the machine.

The cloth to be impressed with the design in iud'ia-rubberis'rolled upon-the cylinder A,

from which itis drawn off and passes upward to cylinder B, against whichit prses and re ceives therefrom athin sheet of rubber, with` which the'surface of cylinder B is consiantly coated by the supply of gn m fed between it and cylinder` G,- as clearly indicated in the' drawing. The cloth, with the continuous sheet of v gum thusspread upon it'on one side, passes between the engravedor printing cylinder D, onwhich the figure to be impressed on the cloth is. raised in relief, and the plain cylinder E, on which is a. thin layer of gum 'laid upon its surface at its junction with cylinder F.`

By this arrangement a. thin coatingr ol" gum is brought upon both sidesof the cloth, and is made 'to adhere thereto in any figure which the raised iigu re or pattern upon cylinder D determines. Thusat one operation the gum is made toadhere on each side ,of the cloth in determined designsat points exactly opposite.

The mode of forming,r the thin layers of gum and taking them from the cylinders is so well knownthat no further description thereof is needed by the practical workman. The gum 4only adheres to the cloth at the points where it has been submitted t'o pressure by the pattern raised upon cylinder '1). Gonsequently the cylinder E takes away all the gum which has not been thus impressed uponl the cloth. From thence the cloth passes up over a small roller an'd down around a second small or oar- 'rying-roller, after which. the side of the cloth that iirst received the coating of `gu m from cylinder AB is passed over the surface of cylinder H, on which there is a slight coating of rubber, to which all the superfluous rubber not im-v pressed by the design on that side'is taken o'.'

I is the counter-cylinder that lays the coating upon H. j The opposite side of the -cl'oth touches the cylinder G, that removes any rub -ber that may chance to escape from cylinderv E. Thelcloth then passes around another small roller, and thence to K, where itis again rolled up with the design imprinted,as above described, thereon. Y Y The cylinders are all driven by gearing en the journalsof the cylinders outside the frame,

the intermediate gear, L, by which they are(l moved, being connected with the driving power.

All the cylinders'are heated, as uSuaLiu-the i manufacture of caoutchouc so as to keen-the gum in a plastic state.

Having thus fully described my invention,

what 1 claim therein as new, and for which I vdesire to secure Letters Paten-t, is

LORIN BERT.
